A while back, I read large portions of the KOMA book and it in the authors talk about how most people can't recognize typography or type-setting in general. People shouldn't be allowed to change margins, line-spacing, fonts, etc.
Since I'm not comfortable making this decision myself, would you be able to recommend some good, Latex-compatible, preferably free fonts?
Nice ligatures and old style numbers are a plus (&, ff, fl, fi).
Also note, I only ever output my Latex files to PDF via
EDIT: I'm looking for a general purpose font for writing prose---mostly letters, reports, books and articles. I'm looking for a font that could just as easily have been made the default. I'm looking for suggestions that wouldn't outrage your if they were made the default in Latex from now on. It should be a Serif font. Something like Georgia, Baskerville, Palatino, etc. But with all the Latex niceties.
